This model is a further development of the classic D locomotive, which was an electric locomotive first built as early as 1925. The D locomotive was a large series with several variants, with the Dm3 being built as late as 1970.

The locomotive was designed for heavy passenger or freight trains, and this model was used throughout Sweden.

A distinguishing feature of this model of locomotive is that the power from two drive motors is driven via a blind axle, i.e. a wheel that does not reach the rails, and then through coupling rods to three drive axles.

This locomotive came to the museum in the 1990s, and operates well in both transport and passenger trains. It can be multi-coupled with the Da 888 locomotive, which is also owned by the museum. Multi-coupling means that two locomotives are coupled together, but are operated by a single driver from the cab of the first locomotive.
